Douglas County Dist. Atty. Christine Kenney Tonkovich said charges against the four suspects arrested in February in Douglas County are pending while an investigation continues. Those who were arrested in Douglas County are Kristine Cave Midyett, 25, Lawrence, on charges of possession of heroin with intent to sell and conspiracy to distribute heroin; Melissa Ann Schultz, 21, Lawrence, conspiracy to distribute heroin; Karen Denise Hanneman, 25, rural McLouth, possession of heroin with intent to sell and conspiracy to distribute heroin; and Chad Elden Reed, 23, Lawrence, conspiracy to distribute heroin and possession of drug paraphernalia.

Two people who were arrested in Wyandotte County on one count each of conspiracy to distribute heroin have been released from jail there on $10,000 bond each, and are scheduled to appear in court at 9 a.m. May 12 for a hearing. They are Kelli Dawne Kennedy, 23, Lawrence, and Jason Richard Bryant, 22, Lawrence.

Information on Brenda Kay Yungeberg, 30, who was arrested in San Francisco on charges of distribution and conspiracy to distribute heroin, was not available.

Charles Peterson, clinical director at the DCCCA Center, said heroin use has increased in the Lawrence area over the past two or three years. About a dozen people, most aged 18 to 25, have sought treatment for heroin addiction at the center in the past year. However, Peterson said, some Lawrence residents may seek treatment at Kansas City-area centers. Heroin addiction usually requires in-patient treatment, which isn't available at DCCCA.
